After reading my post, it even confused me and I wrote it!

What I was asking is what connects part #4 to the outside pin #2 through the arm? It must be something flexible yet precise in length.
LW, you got roller guides? Thats a nice saw, I just have cool blocks and dream of the $150 upgrade to the Carter guides. Don't really use the saw enough to justify the cost though.
I've knocked the guides off my mill twice and at $200 it kinda ruins the day.
